I need to know how to tape the impeller off. i was told that i had to pull the pump apart in order to remove the impeller????

That's what it sounds like. It usually is just a clogged impeller. You'll have to remove the 6 bolts and pull the housing apart. Use a stiff wire to clear the slots in the impeller.

Pull off. Or pry off with two screwdrivers. Or hold it by the impeller and have someone tap the end of the shaft with a brass punch.

Remove impeller housing cover. Insert screwdriver carefully into back of motor to keep the armature from turning then unscrew impeller clockwise or opposite the direction of operation. Replace seal on impeller and pump housing. Lube seal with graphite. Replace impeller and housing cover. Remove screwdriver from motor. You should be good to go.

I have never taken this pump apart.
If I were in your position and I could move the impellar 1/8 turn, the next thing that I would do is carefully loosen the nut on the end of the shaft being careful that nothing else disassembles. Once this nut is loose say 2 turns, try the impellar again watching what is moving. It seems that the nut may have to be removed.
Also, I'm not sure which way the nut of the impellar rotates to remove, but you seem to have that under control since you have it moving already.

Remove the six bolts that hold it together. Pull the half''s apart then pull the diffuser off the front of the back half that is still connected to the motor. Look in the center of the impeller. If their is a screw there it will be a left hand screw, remove it. Now you need to unscrew the impeller. Open the back of the motor and get to the end of the motor shaft. Their are two kinds of motors so use a wrench that will fit yours to hold the shaft and use water pump pliers (Channel locks) to grab the impeller and unscrew. This will come hard at first once unstuck it will just spin off. Pull the rear seal plate off and the back plate will four bolts to remove. With that your done.
When you first pull the six bolts and open the pump you can pull the wires and bring the whole thing to a motor shop or pool store and they will usually just charge for the motor and parts and do most of it there for you.

Based on the limited info. For most jacuzzi pumps, you will need to remove the lock ring and pull the pump apart to expose the impeller/diffuser. Next, remove the diffuser to expose the impeller. Depending on what type of motor you have, either remove the cover plate or cover cap to expose the shaft at the rear of the motor. There are three types of shafts, one is slotted so you will need a large screwdriver to hold it in place. One is larger and can be held with a wrench or special shaft tool. One is more internal and has a switch at the end so it has to be held with a 7/16 wrench under the switch midway between the switch and the housing. You may have to remove the capacitor to gain access with the wrench.
There may be a lock screw holding the impeller to the shaft, if so, remove it by turning it clockwise (left hand threads). Then you can remove the impeller by turning it counter-clockwise. They can get stuck on the threads and you may need an impeller wrench or something suitable to give you some mechanical advantage to remove it.

Change the brushes in the motor.If its running 24/7 then thats your problem.

This is from Danner:
SERVICE AND MAINTENANCE
The housing should occasionally be removed to clean and inspect the impeller assembly. The impeller is the only serviceable item and can be pulled out of the body. If it is worn or broken the entire impeller assembly should be replaced. This will restore the pump to original capacity. Pumps taken out of service for an extended period with fluid inside run the risk of forming a crust which may prevent subsequent starting. Saltwater should be flushed out with fresh water.

IMPORTANT: FOR PUMPS USED IN SALTWATER OR HARDWATER.
Magnet impeller assembly must be removed approximately every 3 months for cleaning in white vinegar to remove accumulations of scale or calcium. Disassemble magnet from impeller by pulling them apart (it may take a strong pull). One end cap will come off. To clean the calcium scale off of the shaft and bearing inside the magnet soak in white vinegar for a few hours and scrape it off. Reassemble magnet/impeller assembly. Do not loose (sic) any washers located between end cap and impeller.

Hope this helps!

HI In most dishwashers, the water pump is located under the lower sprayer arm. This component pumps the water through the dishwasher. The pump has two impellers, top and bottom. These, as well as other components, can become clogged with food or detergent. Here's how to disassemble the pump:

Step 1: Remove the cap that holds the sprayer arm on.

Step 2: Remove the sprayer arm, the screen, the pump housing, a bolt, the upper impeller, the food disposer blade, a spacer plate, the impeller hood, a flat plate, an O-ring, and the lower impeller. Lay the parts out in order as you disassemble them so that you'll be able to reassemble them properly.

Step 3: Clean the parts thoroughly with a mild detergent solution. If any parts are worn, replace them with new ones made for the dishwasher.

Step 4: Replace any seals, such as the O-ring or other washers, with new ones.

Step 5: Reassemble the pump, keeping the parts in order.

To reach the water pump, remove the sprayer arm and screen and then the pump housing. Remove the bolt, and the pump components can be disassembled.

On some dishwashers, the lower impeller serves as a drain pump. This type of system usually has a reversible motor; machines with nonreversible motors have drain valves, as detailed previously. If your machine possesses this impeller pump system, and the water will not drain from the dishwasher, clean the lower pump impeller. This may solve the problem. Otherwise, call a professional service person. 

you will need to pull the front cover off the pump housing in order to inspect the impeller. It is possible that it has failed and just needs to be replaced.
